To all'wkom it may concern:

Be it known that we, WILLIAM B. R001) and ERNEST S. JoHNsoN, citizens ofthe United States of America, and residents of Webster City, Hamiltoncounty, Iowa,have

.' invented certain new and useful Improvemoms in -Heat-InsulatedContainers, of which the following is a specification.

Our invention relates to improvements in heat-insulated containers, andthe object of our improvement is to supply a compact,

portable and convenient device of this type,

inexpensive in construction, easily disassembled for replacements orrepairs, and otherwise most suitable in its construction for containingand keeping liquids orfood for a considerable time at a desiredtemperature.

This object We have accomplished by the means which are hereinafterdescribed and claimed, and which are illustrated in the accompanyingdrawings, in which Figure 1 is a vertical medial cross section of'ourimproved device, and Fig. 2 is an enlarged deof elastic porous orchambered packing filling the interspace of the receptacle B and ofcylindrical form provided near the .opposite ends with stiffening heads2 extend-- container A. C is a cup inverted and fitted upon the.diminished upper part of the container A and covering the exposed top ofthe" neck of the receptacle B with its stopper D.

For convenience in manufacture, assembling and disassembling, the outerreceptacle A. is made in detachably connected sections 1, 4 and 7, Thesection 1 is a hollow drum ing outwardly and also serving as stops forthe overlapping parts of. the top and bottom sections 4 and 7. r

The bottom section 7 is dished, while the top section 4 is conical, witha relatively large central openin having a short conical neck 6 whichfits t e conical neck ofthe receptacle B. closely. The sections may beotherwise shaped to properly conform to the shape ofthe receptacle B andits neck. Sa1d sections may be fastened together detachably whileleaving the container as a whole imperforate, by any convenient ordesirable means, but we have shown in Fig. 2 an instance for the.purpose of illustration. The numeral 5 denotes an angular notch orrecess in an edge part of either sectlon 4 0r 7, receiving a headed stud3 fixed on the margin of the abutting part of the.

drum 1, the stud being received and interlocked with the walls of saidrecess when said parts are overlapped and relatively rotated. Th sbayonet-jointtfastening means is convenient, enabling the parts to beeasily relatively small interspaces which are in effect dead air spaces,homogeneousl distributed and a good non-conductor 0 heat. The corrugatedpieces are in superposed strlps, each strip carrying a thin covering ofpaper onone or both faces which keeps the strips inp'arallel relationwithout nestum'rso sTATEsPAT-antennae.-

ing. For convenience, in the sectional type of container A, abovereferred to, the pieces or strips of material E are properly cut,mounted and fitted within the respective sections of the container, asshown, or otherwise to prepare the device for being disassembled with aminimum of trouble.

This kindof packing is very light and elastic, and cushions well againstshocks from any direction, without settling or vary ing in homogeneity,and renders the device especially useful for carriage on vehicles wheresubjected to many shocks, or for employment .by farmers, mechanics,miners and others, the. container A being provided with a suitablehandle.

AIn case the receptacle B, if made of breakable material, is broken, thecontainer sections maybe readily disassembled to receive another.

Variations in the details of construction 7 the principles 1 Havingdescribed our invention, what we secure by Letspaced from its upper andlower edges and having outwardly projecting headed pins on its outerwall between its end edges and said beads, the said top and bottommembers overlapping the ends of the drum and having angular bayonetslot. connections in their edges to releasably receive and interlockwith said headed pins, and flexible resilient packing elementspositioned separately and independently within said top and bottommembers and said drum to space andycushion a frangible contained vesseltherein and therefrom, permitting assembling and disassembling of saidcontainer parts without displacement of said packing elements.
